COKE-OVEN DOOR.

To all whom t may concern Be it known that I, JAMES A. MGCREARY, a citizen of the United States, residing at Specification of Letters Patent.

edge views thereof. Fig. 5 is an enlarged' detail sectional view of the joint between the doors, and also shows the means for locking Connellsville,'in the county of Fayette and `the door sections together more clearly. Fig.

State of Pennsylvania, have invented certain new and useful Improvements in Coke- Oven Doors, of which the following isa specification. Y

This invention relates to a novel improvement in doors of the character that are especially adapted for use in connection with coke ovens. Y

Primarily the present invention contemplates a coke oven door of the type having upper and lower door sections which may be handled separately or as a unit, and which departs from the usual skeleton-like framework common to doors of this character by providing each section with an imperforate back. In this connection, the invention also proposes to provide an air space between the rear side of the usual tile filling exposed to the heat of the coki-ng chamber and the imperforate metal back, so that heat vwill not be directly conducted thereto but will be lessened by the intervening air gap.

A further object of the invention is to provide a rigid and substantial frame construction for each door section whereby the tiles will vbe detachably and adjustably locked in place, while at the same time providing a novel frameconstruction .whereby the joint between the doors may be sealed and each section securely held to the other to permit of the doors being handled as a unit when desired. j

With the above and other objects in view which will more readily appear as the nature of the invention is better understood, the same consists' in the novel construction, combination and arrangement of parts, hereinafter more fully described, illustrated and claimed. fr.'

A preferred and practical embodiment of the invention is shown in the accompanying drawings, in which-A y l Figure 1 is an elevation of the outer side of the present coke ovendoor, showing the tile filling and tile-engaging and spacing means in dotted lines. Fig. 2 is a vertical sectional view on the line 2 2 of Fig. 1.

Fig. 3 is a horizontal sectional view on the line 3 3 of Fig. 1. Fig. 4 is a composite view showing the removable and replaceable tile units in elevation without the frame, and also showing projected tside and bottom 6 is a detail sectional view on the line G-G of Fig. 5.

Similar reference characters designate corresponding parts throughout the several kfigures of the drawings. v

t By reference to the accompanying drawings, it will be observed that the door forming the subject of the present invention essentially comprises a lower door section 1, and an upper door section 2 having therein an'opening 3 for receiving the hook of a trolley ldevice (not shown). however, is well known in the handling'of coke oven doors, and is utilized to lift the upper section from the lower section when desired to shift the upper section away from the oven door, or handle the entire door as a unit when the upper and ,lower sections thereof are locked together. The opening 3 referred to is preferably closed by a pivoted shutter 4, so that the door may be made air tight during the coking operation.

The said lower door section 1 essentiallyk includes an imperforate sheet metal back 5 which has secured upon its inner face the `oppositely locatedk vertically arranged tile- Patented Oct. 3, 1916.

This device,

engaging bars 6. These bars are preferably spaced from the side edges of said door section to leave projecting cover flange portions 7 which overlap the sides of the oven doorwayto hold they door in its closed posi-- tion, and also assist in forming an air tight joint. The said bars 6 are secured to the back 5 by means of the rivets or bolts 8, and are each provided with an angular tile engaging fiange 9 whichvis preferably disposed at sucha distance from the back 5 that the tile or tiles engagedv thereby are also spaced therefrom.l

The lower edge portion of the door section 1 has fitted to its inner sideV al horizontally arranged adjustable tile supporting and locking bar (see Fig. 2) which has formed at one edgev thereof an angular tile engaging flange 11. The said bar 10 isv adjustably secured to the inner face of the back 5 by means of the bolts 12 mounted in the slots 13 of said back, and works in opposition' to the fixed abutmentl bar 14 at the inner side of the top edge portion of the back V5. In connectionwith the abutmentl Vits'outer side with retaining plate members 17 which coperate with the portion of the abutment bar 14 projecting above the upper edge of the solid'metal back to provide a.

Y keeper groove 18, the purpose of which will hereinafter more fully appear. With further Y24 in the back.

Yreference to the bar 14, it will be observed that the same, like the other tile retaining members 6 and 10, is provided with an angular tile engaging flange 2() which extends throughout the length of the bar, and is adaptedto engage the upper sides of all of the 'tile units held within the lower door section; Y The upper door section 2 is similar in construction'to the lower section 1, and includes an imperforate metal back member 21 having at its upper edge portion an arched vertically adjustable tile locking bar 22, which is mounted on the inner face of the back 21 by means of the bolts 23 fitted in the slots Through the adjustment provided by the slots. 24 the locking bar 22 works in opposition to a fixed abutment bar 25 at the inner side of the lower edge portion of the back 21. The said abutment bar 25 serves as a rigid and fixed support for the tile filling of the upper door section, and engages the tiles thereof by means of the angularedge 26, while the upper edges of the tiles clamped between the bar 25 and the bar 22 are engaged by the angular flange 27 on the bar 22. By reference to Figs. 2 and 5, it will be observed that the abutment bar 25 is secured to the inner face of the back 21 by means of suitable fastening elements 2S, and is also spaced above the extremelower edge of the back 21 to have a downwardly projecting sealing fiange 29.

Therabutment bar 25 above referred" to is preferably provided with spaced slots 30 which are adapted to receiveVr the keeper straps 31 carried by the lower` door section. rlhese straps project through and above the abutment bar 14 of said lower section, as more clearly byV Fig. 5, and also project above and interlock with the abutment bar 25 of the upperl door section, thereby preventing relative longitudinal and lateral movement between the two door members when they are connected and n use. Theupper Vends of the straps 31 are formed with a circular keeper opening 32, adapted to receive the fiat cam end 33 of a locking pin 34 loosely inserted in the opening 35 in the lower edge of the upper door section 2, and which cam 331s shownv eccentric to the circular keeper opening 32 of the strap. The locking pins 34 are preferably provided with an angular handle portion 36 which may be manipulated from the outer side of the door, so that the flat cam end 33 of the pin may be forced into positive engagement with the strap 31 within the keeper opening 32 thereof. Ordinarily the pins 34 are insertedin the upper door section 2 so that the cam end 33 occupies the position shown in full lines in Fig. 6, and as the handle 36 of the pin is forcibly turned, one of the side edges of the cam portion 33 binds or impinges against the side of the keeper opening 32, while the other side edge binds against the top of the bar 25 as shown by dotted lines in this same figure. In this way, the abutment bars 14 and 25 may be securely clamped together. The tile filling for the present door is designated generally as T, and is shown in detail independent ofthe door'in Fig. 4.

From this figure it will be apparent that the tile units 37, 38 and 39 areV provided with curved or arched top portions to fit the adjustable locking bar 22 of the upper door section, while the tile units 40, 41 and 42 of the lower door section are preferably of rectangular formation.V rEhe edges 43 of all the tile sections which abut with each other are preferably fiat, while the other edges which engage with metal parts of the door are provided with an offset metal protecting face'44, and the flange receiving grooves 45. Accordingly it will be apparent that the tile units are 'engaged by the angular flanges on the edges of the adjustable bars 10 and 22, fixed abutment bars 14 and 25, and vertical bars 6, and since the tile engaging fianges of each of these bars are purposely spaced Va desired distance from the inner face of the backs of the door, the tiles whenin assembled position on the door will be spaced from the backs 21 and 5 to provide air insulating spaces A and B. The tiles' 37 and 40, and 39 and 42 are provided with complemental recessed portions 46 and 47 which provide sufficient clearance for the devices that detachably lock the two door sections together. Y

' Vith reference to the placing of the tiles within the door sections, it will be noted that the upper tile units 37, 3S and 39 are clamped in position means of the adjustable bar 22 working in opposition to the fixed bar25. In the lower door section 1, the tiles 40, 41 and 42 are clamped in position through the medium of the adjustable locking bar 10 working in opposition to the fixed abutment bar.14, and in this instance the tiles are also held in position by meansof the oppositely located vertically arranged tile retaining bars 6.

, From the foregoing description it will be apparent that each of the door sections include a tile lling spaced from the solid flange 29. This flange therefore, preventsl air from entering at this point and forms a most effective joint, while the presence of the locking pins 34 working in conjunction with the keeper straps 31 not only increases.

this effectiveness, so that a tight joint may be maintained through the coking operation, but also makes it possible to easily.

break the connection between members when desired.

When the locking pins 34 are in position, and the upper and lower door sections locked together, it will be apparent that the door may be handled as a single unit to be removed from the oven doorway as for instance, during the watering operation. However, should it be desired to remove the upper section only, as when leveling the coal contents of the oven before coking, it is necessary to withdraw or extract the pins 84 so that the end's 33 thereof become free from the straps 31. To facilitate the handling of the upper door section independently of the lower door section, the same is provided with a suitable lever retaining hook 48 for engaging the lever device of the trolley mechanism usually employed in connection with coke ovens, to thus hold the door in a lifted or raised position.

When the door sections are held together in their operative position, it will be apparent that the same cannot move longitudinally or laterally on account of the keeper straps 31 engaging with the bar 25, and it will also be apparent that the backs 5 and 21 of the sections are held in proper alinement by means of the opposite ends of the sealing flange 29 engaging in the keeper grooves 18 formed by the retaining plates at the opposite upper corners of the lower door section. As the door in this form presents a4 solid back, and an effective joint where the two sections meet, it will be apparent that no air can enter the oven through the door itself, and could only enthe door Ater at the edges. However, air is prevented from entering the oven at Vthis point by means of the customary filling of loam or other plastic material being placed in the well known manner.

From the foregoing it is thought that the many features and advantages of the present invention will be apparent withoutl further description, and it will be readily understood that minor changes in the form, proportion and details of construction may be resorted to without departing from the spirit of the invention or scope of the appended claims.
